Congress Investigates Polymarket for Insider Trading on Iran Ceasefire Bets

U.S. lawmakers are calling for investigations into Polymarket after multiple new accounts placed significant bets on a U.S.-Iran ceasefire just before it was announced by President Trump on April 9, 2026. At least 50 new accounts made these bets, raising suspicions of insider trading. This follows a pattern of similar bets tied to other geopolitical events, including a $400,000 profit from a bet on Venezuelan leader Nicolas Maduro's capture. Representative Ritchie Torres has demanded that the Commodity Futures Trading Commission investigate these trades, highlighting the improbability of such accurate predictions without insider knowledge. The situation has prompted concerns about the integrity of prediction markets and their susceptibility to exploitation by individuals with access to confidential information. Blumenthal has previously introduced legislation aimed at regulating prediction markets to prevent such abuses. The current status remains under investigation as lawmakers seek accountability from Polymarket.

Key Points: • Over 50 new accounts on Polymarket placed bets on a U.S.-Iran ceasefire before its announcement. • Rep. Ritchie Torres has called for an investigation into potential insider trading practices. • Previous incidents of suspicious betting on geopolitical events have raised concerns about market integrity.
